    Whirring sound or whinning sound!! Help please

    So I just got my tranny rebuilt.. I had to drive 650 miles after i got it rebuilt, the first 340 miles car drove perfectly fine and sounded great but once it hit like 400 miles i started hearing this whirring sound . The car drives great and gears slip in pretty good but I just dont know what that sound is? I have never heard it until recently and I know its the tranny i can literally hear the gears turning in the tranny and when I slow down I can hear them like if they were next to my ear? How can I stop this noise? Could it be that they rebuilt the tranny wrong or do I need defferent oil we used 80/90 tranny oil!

    Does it whir when in neutral? Does it do it when you put pressure on the stick toward any particular gear? It may be a bad synchro.

    it does it only when its in 1st,2nd,3rd,4th & 5th gear not when I am in neutral. I can hear the gears when Im in neutral slowing down. I have heard ist normal but I just dont know?

    I think you may be overly sensitive since you just had the tranny rebuild. If every gear does it and drives normally, then I wouldn't worry about it just yet.

    Straight cut gears are significantly louder and do make a whirring noise. All modern cars come equipped with helical cut gears. First and reverse are sometimes straight cut for strength.

    what really is weird is the fact that my car never did it before and now its normal for my tranny to make the airplane noise... I guess i really dont mind it its just when i am slowing down and in neutral i can hear the crrk-crkkk -crkk gears slowing down..

    That is exactly how my Evo tranny sounds in 1st when slowing down 'cause the synchro is shot. Kind of like the three stooges. Whooop whoop whoop whop. Seriously.
